Dear All, I am having a problem with using nested EPT in my system: In L0 hypervisor CPUs support vmx and ept; however, L1 hypervisor's CPUs do not have ept capability. Flag 'ept' appears in /proc/cpuinfo of L0 but does not show in that of L1. - 'Nested' and 'EPT' are enabled in L0: $cat /sys/module/kvm_intel/parameters/nested Y $cat /sys/module/kvm_intel/parameters/ept Y - The libvirt xml file used in L0 has this cpu configuration: <cpu mode='host-passthrough'/> - The kernel version I am using for both L0 and L1 is 3.9.11 Thank you very much.
